Im currently boosting my low level shamans. and i have created my accounts so i only need to level 2 x to 60 and 2 x to 30, and then grant the two level 30s to 59 or 60. So my question is, can i use the level 60 accounts to grant when my low levels are level 30? and then boost them all the way to 60?

Guess i should also get enough xp on the 30levels to be around 99% away from 31? so i easily can ding 61?

I read somewhere that as soon as u ding 60 u cant grant levels and u cant get tripple xp?
